United Technologies Corporation (UTC) is an American multinational conglomerate headquartered in Farmington, Connecticut.  It researches, develops, and manufactures products in numerous areas, including aircraft engines, aerospace systems, HVAC, elevators and escalators, fire and security, building systems, and industrial products, among others. UTC is also a large military contractor, getting about 10% of its revenue from the U.S. government.   Gregory J. Hayes is the CEO and chairman. 
In 1974, Harry Gray left Litton Industries to become the CEO of United Aircraft.  He pursued a strategy of growth and diversification, changing the parent corporation's name to United Technologies Corporation (UTC) in 1975 to reflect the intent to diversify into numerous high tech fields beyond aerospace.  (The change became official on May 1, 1975.) The diversification was partially to balance civilian business against any overreliance on military business.  UTC became a mergers and acquisitions (M&A)–focused organization, with various forced takeovers of unwilling smaller corporations.  The next year (1976), UTC forcibly acquired Otis Elevator.  In 1979, Carrier Refrigeration and Mostek were acquired;  the Carrier deal was forcible, while the Mostek deal was a white knight move against hostile takeover designs by Gould.
At one point the military portion of UTC's business, whose sensitivity to "excess profits" and boom/bust demand drove UTC to diversify away from it, actually carried the weight of losses incurred by the commercial M&A side of the business.  Although M&A activity was not new to United Aircraft, the M&A activity of the 1970s and 1980s was higher-stakes and arguably unfocused. Rather than aviation being the central theme of UTC businesses, high tech (of any type) was the new theme. Some Wall Street watchers questioned the true value of M&A at almost any price, seemingly for its own sake. 
Mostek was sold in 1985 to the French electronics company Thomson.
In 2003, UTC entered the fire and security business by purchasing Chubb Security.
In 2005, UTC further pursued its stake in the fire and security business by purchasing Kidde. Also in 2005, UTC acquired Boeing's Rocketdyne division, which was merged into the Pratt & Whitney business unit.
In April 2010, UTC announced that it was investing €15 million ($20 million) to set up the United Technologies Research Centre Ireland in University College Cork which will carry out research on energy and security systems. 
In October 2010, UTC agreed with Clipper to acquire the rest of the company. 
In June 2012, it was discovered that UTC sold military technology to the Chinese.  For pleading guilty to violating the Arms Export Control Act and making false statements, United Technologies and its subsidiaries were fined $75 million. 
In January 2015, UTC Building & Industrial Systems completed the acquisition of CIAT Group, a leading HVAC manufacturing company in France.  In November, Lockheed Martin completed its $9.0 billion acquisition of Sikorsky Aircraft. 
In February 2016, UTC subsidiary Carrier Air Conditioner announced to employees at its Indianapolis plant that Carrier is moving manufacturing to Mexico: “The best way to stay competitive and protect the business for long-term is to move production from our facility in Indianapolis to Monterrey, Mexico.”  In December, Carrier agreed to keep the Indianapolis plant open, keeping 1,100 jobs in Indianapolis. 
On September 4, 2017, proposed to acquire Rockwell Collins in cash and stock for $23 billion, $30 billion including Rockwell Collins' net debt, for $500+ million of synergies expected by year four. 
For the fiscal year 2017, United Technologies reported earnings of US$4.552 billion, with an annual revenue of US$59.837 billion, an increase of 4.5% over the previous fiscal cycle. United Technologies shares traded at over $114 per share, and its market capitalization was valued at US$98.6 billion in October 2018.  UTC ranked No. 51 in the 2018 Fortune 500 list of the largest United States corporations by total revenue.
